Re: VNC server stops responding after a few days
The uncommented line in the hosts file is simply: 127.0.0.1 localhost The default gateway is setup in the Windows IP properties (along with the other static settings) to be 192.168.0.254, which is our modem/router/DHCP server. The modem has an external static IP that we would be connecting to with VNC. I can connect to it on that address and the internal 192.168.0.99 ... The command line on the VNC Viewer shortcut is just the default vncviewer.exe with no options. I just woke up one of the VNC servers/desktops that stopped working over the weekend. I opened the web browser and it took a bit to load; was it asking for an IP renewal? Maybe it's just the power saving options that are at fault: Turn off harddicks: 1hr Standby: 1hr Hibernate: never James Wheaton FloSource, Inc.

Just the usual broadcast traffic... I'm not a networking or Windows expert, but this presumably depends on whether the client (XP?) actually has the VNC server's IP address in its hosts file (something like C:\WINDOWS\system32\drivers\etc\hosts). If it doesn't, then it will send a request to get the address from the DHCP server. If the client ends up using the IP address supplied by the server, then it will eventually expire. I've had exactly this problem on another X server (not VNC). James: what's in your hosts file? And how does the client actually connect to the server? What's the VNC command line? ___ VNC-List mailing list VNC-List@realvnc.com To remove yourself from the list visit: http://www.realvnc.com/mailman/listinfo/vnc-list ___ VNC-List mailing list VNC-List@realvnc.com To remove yourself from the list visit: http://www.realvnc.com/mailman/listinfo/vnc-list
Re: VNC server stops responding after a few days
Hi Phil, The DHCP addresses go from 100 to 253 while the computers running VNC have static IPs less than 100 (99, 98, and 97). James Wheaton FloSource, Inc.

That won't work, because the computer, knowing that it has a static IP, won't request a lease renewal, and after some maximum amount of time, the DHCP server will try to force one. What will happen in this case depends greatly on the software and OS the computer is running, and on the behavior of the router. I'm not a network guy, but I do know that unless your router is more sophisticated than the average small-office router, static IP addresses *MUST* be outside any range of DHCP addresses of your router.

The computer will work in other ways but not with VNC. It's set as static IP, so the router should be giving the same IP after the lease times out. James Wheaton FloSource, Inc.
